![]() ![]() Set the min and max sizes of FFT to 8K and run them in-place (meaning no RAM values would be expected). ![]() You could also test your CPU temperature in terms of how well it delivers power and cools down by pushing the maximum power through the CPU in Prime95. Managing temperatures while running a CPU stress test in Prime95 However, all this still and again requires you to be monitoring the sensors after each significant move. You can also run your clock a bit higher than you would with Prime95 since it makes the system fire on all cylinders and seems to have a lot of safety margin. Prime95 stacks up well against other tools and options (such as a kernel compile) since it keeps the integer and FP units busy and interlinked as opposed to incurring branch misses and I/O waits. (The Blend option is more geared towards the latter). ![]() Our recommendation is to use the Small FFTs setting (as opposed to Blend) for maximum FPU stress and the least possible load on the RAM. Its method for stress testing is pretty fun: it’s part of the GIMPS (Great Internet Mersenne Prime Search) program, and it uses your processor to make big calculations of large prime numbers (hence the word Prime in the name). Your PC should be able to run a torture test on Prime 95 for as long as an average session lasts for you, without any problems or overheating. Prime95 has long been considered a benchmark of benchmarking. Prepare for this, and perhaps aim for it as well, especially if you’re overclocking.
